he amount of 904L steel containing alloy (chromium, nickel, molybdenum) is more than 1.6 times the fake watches 316L, and the key is 904L steel contains a certain amount of copper, but 316L does not contain copper. Two kinds of replica watch steel Rockwell strength (HRB) are ≤ 95, the intensity is almost all 490MPa. So they have no difference in uk replica watches strength and hardness. But 904L steel higher alloy content and add a small amount of copper, making 904L steel than 316L in the corrosion resistance and wear resistance is stronger
